You've gone from mentioning a behavior that you have observed on a few occasions (cyclists apparently deliberately blocking a road, with help from a car - most likely some sort of race training) to stipulating it as the norm, which is clearly not the case. This is like the false premise of the poster above that '[s]ince bicyclists want to own the lane, they'll ride to the outside.' You're both taking examples of the worst behavior by cyclists and generalizing it to encompass all cyclists.
Incidentally, I don't own a bicycle and haven't for a long time, nor am I any fan of rude or irresponsible cyclists, whose existence I happily acknowledge.
